A sex act where a female performs a reach around hand job, but gets on her knees and comes from "down under" aka she reaches up between a man's legs and gives him a ferocious crank as her face is smashed in his butthole. Basically its a race to see if he cums or farts in her face first. Either way the man wins. The hand job can be performed with a traditional grip or Western grip if she wants to get real freaky.

Also referred to as "the Aussie"

After soaking his skin with enough cologne to kill an adult rhino, Clay entered the party looking to hook up with the nastiest, skankiest girl in the room. They went upstairs to have some fun, and to his surprise, she got down on her knees and gave him a glorious Aussie. He pulled off the infamous cum-fart combo, as he squirted a hot load of many gravy at the exact moment he gave her pink eye.

"Guess what guys! Last night this chick gave me the Australian! I farted a giant mud cloud up her nose, then turned around and glued her eyes shut with my man cream. It was awesome!"
